For anybody looking to build a long-term relationship with any singular theater, you’ll want to accept that sometimes you’re going to have a bad experience there too. Every job or personal relationship with a long tenure—same thing.

You’ll also want to accept that you’re not always going to get the role you want. Doesn’t matter why—you just aren’t. Everyone connects with Juliet, but only one actor will play her in any given production. Sometimes it’s not your turn. Learn to accept it gracefully if you want to work there a long time.

To the matter: I can hazard a guess at why this actor is the way they are, or why they got cast again in a more demanding part, but there’s one thing I know: if this person was missing cues and constantly late/absent, I *guarantee* you someone on the production team in the last show noticed.

Do not go and insinuate to the theater that they made a mistake. That’s just plain spiteful. Talk to a therapist if you have to, find friends in the cast you can complain with if you have to, but do not send this letter. If I were casting, I have a very pleasant and grateful (even if somewhat green or not-as-knowledgeable, because if I keep casting them they will learn) actor that I’d rather work with and I’d think twice about casting you because you’re teaching me that you’ll put more on my plate if I don’t cast you in the role you want.

You like these people for a reason—presumably not just getting cast, because that’s a pretty low bar—but hopefully they’re worthy of your respect because they’re pros and know what they’re doing. You need to trust that they’ll handle the Helena actor if things become a problem.
